Ua wānana ka poʻe noiʻi i kahi pūnaewele kalapona hou, e like me ka graphene, akā me kahi microstructure paʻakikī, hiki ke alakaʻi i nā pihi kaʻa uila ʻoi aku ka maikaʻi. ʻO Graphene ke ʻano kaulana loa o ke kalapona. Ua paʻi ʻia ʻo ia ma ke ʻano he lula pāʻani hou no ka ʻenehana ʻenehana lithium-ion, akā hiki i nā ʻano hana hana hou ke hoʻohua i nā pihi mana ikaika.
Hiki ke ʻike ʻia ʻo Graphene ma ke ʻano he pūnaewele o nā ʻātoma kalapona, kahi e hoʻopili ʻia ai kēlā me kēia kalapona kalapona i ʻekolu mau ʻātoma kalapona pili e hana i nā hexagons liʻiliʻi. Eia nō naʻe, manaʻo ka poʻe noiʻi e hoʻohui i kēia ʻano honeycomb pololei, hiki ke hana ʻia nā hale ʻē aʻe.
ʻO kēia ka mea hou i kūkulu ʻia e kahi hui mai ke Kulanui o Marburg ma Kelemānia a me ke Kulanui ʻo Aalto ma Finland. Hoʻopili lākou i nā ʻātoma kalapona i nā ʻaoʻao hou. ʻO ka pūnaewele i kapa ʻia ʻo biphenyl he mau hexagons, square a me octagons, ʻo ia ka mānoanoa paʻakikī ma mua o ka graphene. 'Ōlelo nā mea noiʻi, no laila, heʻokoʻa loa ia, a ma kekahi mau mea,ʻoi aku ka makemake o nā waiwai uila.
No ka laʻana, ʻoiai ua waiwai ʻia ka graphene no kona mākaukau ma ke ʻano he semiconductor, ʻoi aku ka maikaʻi o ka ʻoihana kalapona hou e like me ke metala. ʻO ka ʻoiaʻiʻo, inā he 21 mau ʻātoma wale nō ka laulā, hiki ke hoʻohana ʻia nā kaha o ka pūnaewele biphenyl e like me nā kaula conductive no nā mea uila. Ua kuhikuhi lākou ma kēia pālākiō, e hana mau ana ka graphene me he semiconductor.
Ua ʻōlelo ka mea kākau nui: "Hiki ke hoʻohana ʻia kēia ʻano hou o ka pūnaewele kalapona ma ke ʻano he anode maikaʻi loa no nā pā lithium-ion. Ke hoʻohālikelike ʻia me nā mea graphene i kēia manawa, ʻoi aku ka nui o ka hiki ke mālama lithium. "
ʻO ka anode o kahi pākahiko lithium-ion ka mea maʻamau i haku ʻia me ka graphite i pālahalaha ʻia ma luna o ke keleawe keleawe. Loaʻa iā ia ka conductivity uila kiʻekiʻe, ʻaʻole pono ia no ka hoʻohuli ʻana i nā ion lithium ma waena o kona mau papa, akā no ka mea hiki ke hoʻomau i ka hana no nā kaukani o nā pōʻai. ʻO kēia ka mea e hana ai i kahi pākaukau maikaʻi loa, akā hiki ke hoʻomau i ka manawa lōʻihi me ka hoʻohaʻahaʻa ʻole.
Eia naʻe, ʻoi aku ka maikaʻi a me nā mea liʻiliʻi e pili ana i kēia pūnaewele kalapona hou hiki ke hoʻoikaika i ka mālama ʻana i ka ikehu. Hiki paha kēia i nā kaʻa uila a me nā mea hana ʻē aʻe e hoʻohana ana i nā pākahi lithium-ion i liʻiliʻi a māmā.
Eia nō naʻe, e like me ka graphene, ʻo ka noʻonoʻo ʻana i ka hana ʻana i kēia mana hou ma ke ʻano nui ka paʻakikī e hiki mai ana. ʻO ke ʻano o ka hui ʻana i kēia manawa ke hilinaʻi nei i kahi ʻili gula maikaʻi loa kahi i hoʻokumu mua ʻia ai nā molekala kalapona i nā kaulahao hexagonal pili. Hoʻohui nā hopena hope i kēia mau kaulahao e hana i nā ʻano huinaha a me nā ʻano octagonal, e ʻokoʻa ka hopena hope mai ka graphene.
Ua wehewehe ka poʻe noiʻi: "ʻO ka manaʻo hou e hoʻohana i nā precursors molecular i hoʻoponopono ʻia e hana i ka biphenyl ma kahi o ka graphene.
